Supramolecular chemistry Essay Example

Supramolecular chemistry

The tiny size of the hydrogen atom creates a high affinity for the other electrons thus the combinations tend to aligned in certain direction.Coordinate bonding is another form of chemical interaction that involves the bonding between ionic form of metals and atoms that are concentrated with electrons. The force involved in this process is relatively low but the theory of alienation of the structure in a certain direction is relevant. The Van der Waals chemical bonding is yet another form of molecular recognition of the molecules. In contrast, it forms a weaker bonds and the structure is not formed in any certain direction. It involves all types of molecules as the attraction depends on the dipoles created by the presence of unevenly distributed electronic particles in a neutral element. The overall effect is felt by the combined force of all the electronic interactions in the chemical component and not by the sole interactions of individual particles. The shape of the molecule is significant since it forms a lock and key assembly that is very effective in its combination.Hydrophobic interactions on the other hand, involve media that are aqueous in nature. The molecules are usually hydrophobic and they come together to form complex structures as evidenced by the cell membrane. The mechanism behind the formation is complicated as it does not include the attraction of the molecules themselves but points to the hydration framework around them. Water by itself is formed when its molecules combine to create hydration layers that are chemically important. Hydrophobic molecules come together to eliminate the amount of water molecules present in the hydration layers. The elaborate process involved in this interaction is still not explained comprehensively and is under debate. Lastly, pi-pi interactions are seen in aromatic rings with mention of the electronic orbital. A form of energy stimulation is experienced when the aromatic rings face one another and they criss-cross the pi-electron orbital. This is clearly observed in the DNA structure where pi-pi bonding occurs between neighboring base pairs.Host-guest chemistry is a branch of molecular chemistry that involves the molecular interactions, and includes a host and a guest in its overall definition. A host can be said to be a type of receptor molecule that binds to the guest. It is a chemical entity with viable binding sites available for interaction by the guest. A complex is formed
